A centre bar roller buckle for 25mm (1in) straps, with a curved frame and a broad, rounded bar at the back. Nickel plated.
The pin sits on a fixed centre bar, so the strap fastens through a punched hole and the loose end needs a keeper. The roller on the front bar lets the strap pull through without scuffing, and the curve in the frame helps the buckle sit close to the strap. It suits dog collars, bag straps, narrow belts, and tack.
